I'm a fairly experienced player though I don't get nearly as much practice as I'd like. I usually DM/GM when I play and I've be itching to be a player again and actually enjoy tabletop once more. I like to play difficult combinations of race/class that provide a challenge for me and a combination of entertainment and support for the party. I'd rather not be leader but I tend to get stuck with the role too often for my taste simply because I understand tactics and combat.
Among my favorite characters were a Gearforged Paladin (loved it, was a zealous do-gooder made of metal and faith) and my pride and joy was a doppelganger chameleon from D&D 3.5 (i had all the perfect prestige classes and would shift forms and roles like a champ).
I would love to play a campaign where the details matter and the DM/GM likes innovation and intelligence from their players rather than some permutation of several simultaneous hack'n'slash solo-games that are somehow fused into a haphazard storyline desperately trying to refocus everyone every session.
I don't mean to sound too whiny there but I have experienced this kind of group as a DM/GM and grew to despise tabletop over time due to the absolute nonsense games would evolve into. I hope a good gaming group is out there. Thank you for reading and happy hunting.
